Get Your Head in the Game




Football field yard line

Fall means football among my family and friends. From local youth teams to collegiate programs to professional organizations, we love them all. As winter begins, we head into the championship series for all these teams, and it is hardly a controversy-free event, whether it means a bad call during a game, questionable rankings, or even unfair recruiting practices off the field. But, lately, one of the biggest controversies in football has been related to mental health. The incidence, risks, and consequences of concussions related to football seem to be on the rise and a debate is raging about what can and should be done about it.

This fall, the Institute of Medicine (IOM) and the National Research Council (NRC) published findings of a year-long review of sports-related concussions in youth athletes. This coupling of sports and medicine has generated a high-profile and hotly-contested examination of head injuries in sports. There is confusion and disagreement about how to define a concussion, as well as how concussions affect future injuries, when it is safe for a player to return to the field, and the effectiveness — or lack thereof — of protective equipment. The diagnosis, treatment, and long-term consequences of concussions are also in question.

Concussion involves a complex physiological process, but it is generally defined as a traumatically-induced disturbance of brain function. Concussion is a subset of mild traumatic brain injury, which is at the less severe and self-limiting end of the brain injury spectrum. An estimated 3.8 million concussions occur every year in the United States during competitive and recreational sports, and as many as 50% go unreported. Certain sports and positions offer higher risks of concussions, and the highest incidence of concussions occurs in football, hockey, rugby, soccer, and basketball. Previous concussions increase the risk for repeat and more severe concussions.

Part of the controversy is owed to the fact that experts and clinicians cannot even agree on what really causes a concussion, let alone how to consistently diagnose and manage one. Prevention is another point of contention, and protective gear already in use, such as helmets, has not been shown to decrease the incidence or severity of concussions. The long-term consequences of concussion are debated, but evidence seems to be mounting that repeated blows to the head are leading to long-term physical and mental health consequences. Concussions may accelerate the progression to negative cognitive, psychiatric, or mental health outcomes. For instance, depression is more likely to occur in football players who sustained concussions during their professional careers; the more concussions, the greater the likelihood of depression. Similar conclusions have been reported with cognitive impairment, premature aging of the brain, and dementia.

Concussion can also lead to physical, emotional, and sleep problems. While symptoms of a concussion usually resolve within 2 weeks with physical and cognitive rest, some symptoms may persist for months or years. Pre-existing mood disorders, attention-deficit disorders, and headache disorders complicate the diagnosis and management of concussion.

There are no evidence-based guidelines for disqualifying an athlete from returning to play after a concussion, though most athletic associations have themselves implemented rules for coaches, players, and sports medicine physicians to follow. However, skeptical observers believe that conflicts of interests between these parties, who are all interested in a winning team and may not follow the guidelines, may put players at increased risk of injury.

The IOM/NRC report acknowledged that education is paramount to addressing and correcting concussion-related consequences in sports. Players, parents, coaches, and physicians should all be educated about identifying and managing symptoms of a concussion. Prevention efforts also need to be considered. But, there is also a need for a change in culture and attitude when it comes to sports injuries. Players need to self-report concussion symptoms on a more regular basis, and adherence to return-to-play guidelines is critical. Social norms about acceptable athletic risks and behaviors may also need to change, according to many experts. Tougher is not always better, and getting hit harder does not always make you stronger.

While almost no one in America wants to see the gridiron turned into an emasculated field of gentle taps and easy passes, we do owe some consideration to the future mental well-being of the men that play the games we love to watch.

    Is fish oil as a pretreatment and post treatment a viable option?
    Or is more research needed?
    This is a rat model so we have to account for the rodent model in inflammation is not the same as humans.

    Jennifer & others,

    The contact sports you mentioned reveal many concussive forces; & concussions often happen as a result of not just direct blows to the head! We understand fully how the brain within the skull reacts to significants impacts imapacts to the upper body as it rattles around the skull a number of times until it comes to rest.

    Concussions in my area are more frequent in women’ basketball which is played at a very competitve manner. I know of a 16 yo f athlete who experienced 5 well-documented concussions in 5 years; before she switched to running track. My significant issue rests w/ coaches, trainers, & physcians who examined her & allowed her to continue this pursuit. Even her parents did not object?

    For me clinically, the brain is the most significant body organ. It gives rise to the sense of others, to the self & the mind. So the stakes are so very high.

    As a 25 yr. soccer referee, I have gotten heading banned, in a local soccer organization for U 14 & lower based on my clinical concerns.

    Very timely & pertinent article!

    Rich
